About Rio Tinto

• Rio Tinto is one of the world’s largest mining groups
• With headquarters in London, Rio Tinto has operations around the globe and major hubs in the United States, Canada and Australia
• Major products include aluminum, copper, diamonds, coal, uranium, industrial minerals (borax, titanium dioxide, salt) and iron ore
• Most operations are in North America and Australia, but Rio Tinto has significant businesses in Asia, Europe, Africa and South America
• Rio Tinto never owned or operated the Holden Mine. Intalco Aluminum Corporation, a successor to the Howe Sound Company, is responsible for the cleanup. However, through the 2007 acquisition of Alcan (formerly a part owner of Intalco), Rio Tinto agreed to pay for and manage the cleanup on behalf of Intalco. Intalco and Rio Tinto are separate companies.
• Rio Tinto has an excellent track record of mine development and closure, as well as in the cleanup and remediation of historic mining properties, such as Holden
